./configure: line 22468: syntax error near unexpected token `sasl,,'

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

I have already install libmemcached using

sudo yum install libmemcached

Answer 1

On Ubuntu, try doing:

sudo apt-get install libsasl2

sudo apt-get install libsasl2-dev

Answer 2

I think you need to install memcache-client instead.

gem install memcache-client

and you will see this:

1 gem installed

Answer 3

I encountered this issue trying to install the memcached gem on Amazon's AMI Linux.

I resolved it with installing both cyrus-sasl and cyrus-sasl-devel:

cyrus-sasl.i686 : The Cyrus SASL library
cyrus-sasl-devel.i686 : Files needed for developing applications with Cyrus SASL

as well as, and this is key:

gettext.i686 : GNU libraries and utilities for producing multi-lingual messages
gettext-devel.i686 : Development files for gettext

Once these were installed

sudo gem install memcached
Building native extensions.  This could take a while...
